SPECIFICATION forming part of Letters Patent No; 258,297, dated May 23, 1882. l

.To all whom @t may concern:

Be it known that I, PAULINA M. L. HERsE, of the city of Buit-alo, in the county of Erie and State of New York, have invented new and useful Impovements in Grain and Gockle Separators, of which the following is a speciiication,refrence being had to the accompanying drawings.

This invention relates to thatclass of grainseparators which consist of a revolving cylinder provided on its inner surface with indentations, cells, or pockets in which the small grains embed theniselves,and are elevated by the rotation of the cylinder above a trough arranged within the cylinder into which the small grains are discharged, while the grains which are too large to enterl the"v pockets or cells roll back on the lower partof lthe ascending side of the cylinder, and are finally discharged over the tail end of the cylinder.

The object of my invention is to construct a machine of this Vclass in which both oats and cockle are effectually separated from the wh eat; and myinvention consists of the mechanism whereby these results are accomplished, as hereinafterfully set forth.

In the accompanying drawings, consisting of four sheets, `Figure 1 is a longitudinal section of a grain-separator provided with my improvements. Fig. 2 is a top plan view thereof. Fig. 3 is a horizontal section through the axis of the separating-cylinders. Figs. 4 and 5 are end views of the machine. Fig. 6 is a longitudinal vertical section, and Fig. 7V a horizontal section of a modied construction ot' the machine. Fig. Sis a cross-section in lline z z, Fig. 6. Fig. 9 is a longitudinal fragmentary section of the separating-sieve. Fig. l0 is a fragmentary top plan View thereof with a portion ofthe perforated plate broken away.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame ot' thc machine, and B Cthe separating-cylinders, arranged one behind the other in a slightly-inclined position in the frame A. The cylinders are preferably arranged in the same axial line, and secured together by a short cylinder, C', of slightly larger diameter. C are supported by means of rings or circular rlhe cylinders B iiang'es b upon 'groovcd rollers d, which arcsecured to two parallel shafts, d d2, journaled in bearings in the frame A. The shaft Z is provided at its end with a bevel-wheel, D, which is driven by a bevel-pinion, D', mounted on a horizontal shaft, e, to which power is applied in any suitable manner, and whereby the cylinders are rotated in the direction of the arrow in Figs. 4 and 5.

The cylinder B is provided on its inner surface with cavities, cells, orV indentations of a size which germits the round grains of cockle and similar small seeds to lie in these cavities and to be elevated by the rotation of the cylinder, while the larger grains of wheat are rejected and roll back on the inner surface of the cylinder. The cylinder G is provided on its inner surface with cavities, cells, or inden-` tations of larger size, which permit the grains "i lseparated from the grain, the latter passing through the meshes of the sieve, while the foreign matter is discharged over the tail end ot' the sieve. The sieve F is preferably y, composed of a sand-sieve, h, which permits only the ne sand to pass through its 1neshes,while the grain passes onto the next section, h of the sieve F, which permits the smallest wheat and cockle and similar small grains and seeds to pass through its meshes, while the rest of the grain passes 011 to the last section, h2, which permits thelarger wheat to passv through its meshes, while the largest wheat and oats pass over the tail of the sieve F. The small wheat,

cockie, and small seeds, which pass through the second sectiomh, of the sieve F, fall upon the inclined bottom plate, of the sieve, and are. conducted by a spout, I, to the c-ylinderB. The largest wheat and oats, which pass over the tail of the sieve, are conducted by a spout, K, to the cylinder C. The medium-sized wheat,

IOO

which passes through the section h2 of the sieve F, falls upon an inclined bottom, Z, and is conducted by a spoilt, L, to the grain-trough M of the cylinder C.

f' represents transverse stationary bars, rods, or wires,which are arranged underneath the sieve for the purpose of preventing the wheat and oats from lodging in the perforations of the sieve. The bars or wiresf are arranged so closely together that the shaking motion of the sieve will bring each perforation over oneof the bars or wires,and thelatterarearranged so closely to the under side of the sieve that they will come in contact with the point of any kernel of grain which may have lod-ged in an opening and displace such kernel, as indicated in Fig. 9. The bars or wiresfl do not oier any obstruction to the free passage of the round grainssuch as cocklc-through the perforations of the sieve.

The sieve F andthe grain-conduitsattachedthereto receive a shaking' motion by an eccen tric or crank, p, mounted on a transverse shaft, p,vand connected with the sieve by a rod, p2.

N represents the cockle-trough, arranged in the cylinder B, and n m the catch-boards connected with vthe troughs N M, respectively, in the usual manner.

a is a conveyer arranged in @the trough N to deliver the cockle which is deposited iu this trough at the outer or higher end of this cylinder, and m is a conveyer arranged in the trough M to deliver the grain which is rcceived in said trough at the outer or lower end of this cylinder. The two conveyers n fm are mounted upon the same shaft, which is driven by gearwheels a2, or by any other suitable means.

o are depressed cups or pockets, which are -formed between the cylinders B and C in the short cylinder C', which connects the two cylinders. The grain which passes over the tail of the cockleseparator B falls into the pockets 0, whereby it is elevated and deposited in the grain-trough M of the oats-separator O.

o' is a circular flange or ring, arranged on the inner side of the cylinder G, between the latter and the pockets o, for the purpose of preventing the grain which is discharged from the'cylinder B from entering the cylinder C.

o2 is a stationary partition, arranged at the tail end of the cylinder B, for preventing the wheat from returning into the cylinder B.

Q represents an ascending air-trunk, into which the grain is delivered from a hopper or box, g, before the grain passes to the sieve F, and which is connected with the eye of a fan, R, by means of horizontal spouts q g3 and a chesshopper, q2.

S is an ascending air-trunk, into which `the grain is delivered from the trough M of 'the separating-cylinder C by a spout, s. rllhe airtrunk S is connected with the eye of the fan R by horizontal air-trunks s s3 and a ehesshopper, s2. The fan is rotated by a belt, r,-

lfrom the shaft p.

The operation of my improved machine is as follows: The grain is first spouted into the air-trunk Q, where it is freed by the air-current from the lightimpurities. The grain falls from the trunk Q upon the sieve Q,where it is freed from the straw, sticks, stones, and other large impurities. From the sieve g the grain passes upon the sieve F, where it is divided into three different grades, the iirst grade comprising the cockle and small wheat, the second middle-sized wheat only, and the third large wheat and oats. The first grade passes into the cylinder B, where the coekle is separated from the wheat, the eoekle being elevated and delivered into the trough N, from which it is removed by the conveyer a', while the wheat rolls back and escapes iinally over the tail end ofthe cylinder. The third grade passes into the cylinder C, wherein the oats are separated from the wheat, the latter being elevated and delivered into the trough M, from which it is discharged by the conveyer m', while the oats roll back and escape over the tail of the cylinder C. The wheat which escapes over the tail ot' the cylinder B is elevated by the pockets 0 and delivered into the trough M, where it is commingled with the wheat from the cylinder C, and the second grade of wheat from the sieve F, which contains neither coekle nor oats, is also delivered into the trough M by the spout L, so that the conveyer m discharges all the different grades of wheat toA gether into the air-trunk S, when the light impurities which have been detached from the kernels in their passage through the machine are separated from the grain by the air-cur. rent.

Instead of the pockets o, whereby the wheat is transferred from the cylinder B to the trough M, openings may be substituted, which permit the escape of the-wheat from the tail end of the cylinder B; but this arrangement is not as desirable, because the wheat is then discharged at two different points.

The spouts I, L, and K are provided with valves t t', whereby the grain may be directed from one spout into another, so thatit thegrain operated upon should contain no eockle the small wheat, which passes through the section 7L' of the sieve F, can be delivered into the spout L and conducted by the latter directly to the grain-trough M ot' the oat-separator C without first passing through the cylinder B, and if the grain should contain no oats the third grade of grain, which passes over the tail of the sieve F, can be, directed into the spout L, and both the second and third grades delivered directly into the conveyer-trough M of the cylinder C.

Instead of arranging the two separating-cylinders one behind the other, they may be arranged side by side, as illustrated in Figs. 6,

7, and 8.

Although I prefer to divide the grain into three different grades by the sieve F, it is not absolutely essential that this should be done,

since the grain may be divided into two grades,

the small grain carrying the cockle with it and the large grain the oats.

I claim as my invention- 1. In a grainseparator, a cylinder composed of two or more sections arranged end to end and provided VWith cavities, cells, or indentations of different sizes, and independent discharge mechanism for each section of' the cylinder, substantially as set forth.

2. The combination, with the cylinder B, provided o1`i its inner surface with indentations, cells, or pockets which admit the cockle and rejectrthe wheat, and the cylinder C, forming a continuation of the cylinder B, and provided on its inner surface with indentations, cells, or pockets which admit the Wheat and reject the oats, of pockets or cups o, which are interposed between the cylinders B and C and receive the wheat from the cylinder B and deliver it into the wheat-discharge trough of the cylinder C, substantially as set forth. Y

3.v The combination, with the cylinder B, provided on its inner surface with indentations, cells, or pockets which admit the cockle and z 5 reject the wheat, and the cylinder G, provided on its inner surface with indentations, cells, or pockets which admit the wheat and reject the oats,of a preliminary grading apparatus,where by the grain is divided into three different 3o grades according to size, and mechanism whereby t-he smallest grains are delivered into the cylinder B, the largest grains into the cylinder C, and the medium-sized grains into the Wheat-,discharge trough of the cylinder C, sub- 3 5 stantially as set forth.
